Index From Snapshot operation in an SLP
The Index From Snapshot operation indexes the contents of existing snapshots. When NetBackup indexes a snapshot, it creates an image catalog file in the NetBackup catalog for each snapshot. The presence of an image catalog file assists the user when a file needs to be restored from the snapshot, as described in Table: Restore operations.
The Backup From Snapshot operation also creates an image catalog file. An Index from Snapshot may not be required if a Backup From Snapshot occurs frequently enough for the restore needs in your environment. For example, if the Backup From Snapshot runs once per week but file restores are required daily, consider using the Index from Snapshot.
Table: Restore operations
Type of restore
Live browse restore
The user navigates the directory structure to locate and select the files for restore.
No image catalog file needs to be present in the NetBackup catalog.
During a live browse restore, NetBackup automatically mounts the snapshot so that the user can see what files it contains. Mounting and unmounting the snapshot can be time-consuming.
If an image catalog file is present, NetBackup does not mount the snapshot.

The image catalog file must be present in the NetBackup catalog.
Table: Index From Snapshot operation characteristics
Storage unit selection
The Index From Snapshot operation does not write data to a storage unit. However, a storage unit selection is needed to select the media server that to be used to access the snapshot. As a best practice, use the storage unit from the Snapshot or Replication operation that is the source for this operation.
When an Index From Snapshot operation appears in an SLP, it must be the child of a Snapshot or Replication operation.
Therefore, click on either a Snapshot or a Replication operation in the SLP when adding an Index From Snapshot operation.
While an Index From Snapshot operation cannot be the source for any operation, a Replication operation can follow it.
The Index From Snapshot operation can consume system resources and requires that each snapshot be mounted to create the image catalog file.
Consider the following items before using the Index From Snapshot operation:
Standard, MS-Windows, NDMP, and VMware backup policy types support the use of storage lifecycle policies that contain the Index From Snapshot operation.
The Index From Snapshot operation can run from a full or an incremental schedule. The file entries that are added to the image catalog file for either schedule are the full set of files since all files can be restored from that snapshot. To do so allows for the most efficient restore, however, more space is consumed in the NetBackup catalog by the image catalog file.
